Carbon Dioxide Fixation by Algal Cultivation Using Wastewater Nutrients

Abstract: Chlorella vulgaris was cultivated in wastewater discharged from a steel-making plant with the aim of developing an economically feasible system to remove ammonia from wastewater and from Ñue gas simultaneously. SinceCO2no phosphorus compounds existed in wastewater, external phosphate (15É3È 46É0 g m~3) was added to the wastewater. After adaptation to 5 % (v/v) theCO2,growth of C. vulgaris was signiÐcantly improved at a typical concentration o
